在近幾年的高考試題中，對it的考查成了一個不可忽略的考點(diǎn)，它主要涵蓋了以下幾個方面：

A. is it B. is there C. are they D. are those

2. The doctor advised Vera strongly that she should take a holiday, but ____ didnt help. (2005全國卷Ⅲ)

A. it B. she C. which D. he

答案為A。but是并列連詞,所以逗號前后的兩個句子是并列的,后一個分句的主語是it,指代前面的分句The doctor advised Vera strongly that she should take a holiday.
